★★★★★ Very good mobile operator. Good internet connection.

★★★★★ You have weaknesses in your network some time the signal is lost when travelling by train, but you can improve your network by using the fiber lines close to the rail train in big area, also I think the customer service is not bad and can be improved. Thanks said Alramadneh telecom expert

★★☆☆☆ Unable to refund an accidental subscription after 3 days have passed. Where is it written? Even the support employee knows not. It just is. When you search for the usual amount of days in which a payment can be returned, a website will usually say 7–10 days at the bare minimum, but apparently any company with a red and white logo in Russia couldn't care less about informing their customers in visible ways.

★★☆☆☆ Installed it after I got a message from the provider that my purchase from a card was unsuccessful and there was a link to open to read the full message. Phone has enough memory and isn't old, but the app just crashed. (Also, for god's sake, please do something about the fact that your cell coverage is awful! A couple km out of the city, and you lose any kind of connection, much less mobile data, which isn't an issue for literally almost every other provider in Russia.
